To all whom it may concern Be it known that l, JAMns A." GRAY, a

citizen of the United States, residing at. the city and county of San Francisco and State of California, have invented certain new and useful llmprovementsfm Apparatus for Rea-Forming Can-Bodies, of which the following is a specification.

The present invention relates to amachine for reforming can bodies, and more par ticularly for restorin such can bodies to their originalcylindrlcal shape after they have been flattened, as for shipment and storage. I

Forreasonsof economy, the bodies of cans designed to be used for the rece Mon and preservation of food products or ot er material are first made in cylindrical form, and

i then flattened by compressing opposite sides,

in order that such can bodies may occupy less space durin shipment and storage. it is necessary, is erefore, to restore these flattened can bodies to their original cylindrical shapebefore the first end'or bottom can be coating thereof. In order to fullycomprehend the inven tion, reference should be had to the accom-- panying sheets of drawings, in whichbill applied thereto The machine embodying the present invention accomplishes this reformation of flattened can bodies, and may be used, for example, by a packer who has i received and stored his'supply of cans, for

the seasons pack, in flattened form.

The object of this inventionis to-provide a machine for the above described purpose,

which will reform flattened can bodies without in anyway injuring the same, as by dis: rupting the metal or destroying the surface Figure 1 is a perspective View of the can reforming machine, certain parts being broken away, and others beinggshown in phantom, to illustrate all the component parts of the machine and the relations therebetween.

Fig. 2 is a part-sectional elevation taken in the direction of thearrows in a plane represented by the line m-mpf F1 1.

I Fig. 3 is a vertical section ta ten in the direction of the arrows along the Huey -31 of Fig. 2, certain parts being broken away for the sake of clearness.

' in the drawings, the numeral 1 represents any suitably constructed base or bed-plate, made or" cast-iron or o her suitable material,

super-structure 3 and the bed-plate 1.

-2,Fig. 1 of the drawings. Mounted upon the bed 1, is a suitable super-structure 3, in which is journaled a horizontal drive-shaft 4:. This shaft t constitutes the main driving meansfor the entire machine, and is shown in Fig. 1 of the drawings as carrying a beltpulley 5 at one end, by means of which said shaft 4 may be driven.

A mutilated worm 6, meshing with a worm-wheel 7 mounted upon a shaft 8, imparts an intermittent rotary movement to saidshaft .8. The shaft 8 is journaled in a superstructure 9, which is supported by the A. turret 10, in the present case mounted in a plane for vertical rotation, is secured to one end-of the shaft 8, and atregular intervals about this turret l0, and near the periphery thereof, 1s a serles of fixed outwardly projeoting studs 11,-Fig. 2 of the drawings.

"Mounted for free rotation upon each stud 11 is a cylindrical mandrel 12, formed as shown in Fig. 2 with atapering or conical endjpon tion 12. Eiuitable means are employed for retaining the mandrels 12 upon their respective studs 11, said means being shown in the dra-wingsas comprising a screw 1? in the free end of each stud l Amther horiziintal shaftlt,-Figs. i and 3 of the drawings, parallel to the shaft 8,

is journaledin brackets 1? and 18 supported by the {bed-plate l, and is continuously driven by the drive-shaft a through suitable bevel gears 15and 16. A yoke 19'is pivoted into position by the intermittent rotation of the turret 10. This contact between the roller-2O and one of the mandrels' 12 is preferably secured by meansof a plate a24t,Fig.

2 ofthe drawings, slidably mounted upon plate 1, said plate Qtbeing pressed upward by springs 26, and supporting the free end of the yoke 19 by means of the pins 27.

I ets 2 8,Fi g's'. 1 and 3 of the drawings, which support, by means of angle brackets 29, a magazine or holder 31 for holding a supply of flattened can bodies 32 to be reformed when required for use. Said magazine 31 preferably comprises two opposite vertical side-plates fastened to the brackets 29, and four vertical angle-plates 31 fastened one to each edge of each side-plate 30. The lower part of the magazine 31? is formed upon two sides by the oppositely disposed plates 33,Fig; 3 of the drawings, which have inwardly projecting flanges 33 upon which the lowermost flattened can body may rest, and upon the other two sides by a stripper plate '30, formed as shown in Fig. lot the drawings, and an oppositely disposed plate -30",- -Figs. 2 and 3 oi." the drawings, the function of said plates 30 and [30" being to guide the lowermost canbodies whilev the same are being spreadjust prior to removal from the magazine, 1 n

immediately beneath the magazine" thus formed" is a horizontal guide-plate 34, in the guide-waysj36 ot-which is carried a sliding me her 35,Fig.' 1 of the draswrings. Horizontal means, shown in Fig. l,.asconsistingota and a lever 38 connected to said lug 37' by a link 39, said lever being fulcrum'ed at 40* to a bracket tached to the frame of the of a cam 62 attached to said drive-shaft 4.

machine, and connected by a rod 41 to an eccentric strap- 42 which 'embracesan eccentrio 43 on the drive shaft 4.

Attached to the slideBSfare "two spaced horizontal pointed rods '44:, and between and parallclto said rods, and also attached to the slide 35 a cylindrical horn 4L5, "formed-preferably with a flattened, two-' prongedend. The rods 44 and the horn 45 are adapted to be introduced through suitable openings in the stripper plate 30, by the inward motior'rof the slide 35, between the sides of a flattened can body 32, in order to'partly spread the same prior to the removal thereof from within the sphere of the magazine or holder, as illustrated in Fig. 2 of the drawings. A pair of pusherrods tfiare also attached to the slide 35 imhit ' gage the lowermost partially spread and released canhody. 3-2 and force'the sameover a oositionedmandrel 12,, are-shown in a i a containsa supply of flattened can bodies 32, .Qn each side ot'the mag 2139*31 is a Qand 3 ofthe drawings.

each of said arms-being provided with an inwardly extended lower end having an in clined face 50 and a notch '52in'said face. These inwardly turned ends of thearms 4t? and 4:7 are adaptedtofhe inserted into the to the superstructure of the machine.

iprocating motion may be ims parted to the slide 3-5'by any (convenient the entire stackof flattened can bodies 32 within said magazine, duringa portion of the cycle of operation of the machine, and,

.by means of the notches 52, to engage and slightly spread one of the lower can bodies, in order to permit of the entrance of the spreader rods 44 and the horn 45 as hereinbefore described.

The swinging arms 47 are fixed upon a short shaft 48, journaled in an extension of one of the brackets 28,and which carries an upwardly extending lever-arm 53. The opposite swinging arms 47 are fixed to a shaft 49, journaled at one end in an extension of the opposite bracket 28 and at the other end in a bracket 56 suit-ably attached shaft 4:9 carries a depending lever-arm 5t,

which is connected to the lever-arm 53 of the shaft 48 by the link '55, so that rotation of one shaft produces an opposite rota- ,tion of the other, and the arms 47 and 47' are thereby caused to swingin' opposite directions. The shaft 49 is given a reciprocati'ng rotating movement by any suitable means, as, .tor example, a lever 57 attached to said shaft 49, 'a rod 581 loosely attached to said lever 57., and a yoke 59 on the lower end of the rod 58, said yoke straddling the drivershaft 4: and havinga cam-follower 60 adapted for engagement with a groove 61 the forward or turret end 63 of which; is

mounted a radially extended ejector arm 64,

which is adapted to engage the inner edge of a reformed can body for the ejecting ot the same from its supporting mandrel. this rod is caused to slide longitudinally at certain periods in the cycleof operation of the machine, by alever 67,- Fig. 1 of the-drawings, connected by a link 66' to a sleeve 65 mounted upon said rod 63. This lever 67, is fulcrumed at 68 to asuitable bracket 69 attached to the frame of the machine, and its lower-end is connected by a pin 7 0 to a connecting rod 71, the other end; at which is pivotally attached to the reciprocating'lever38. v

The operation of the machine'may be described as follows .hssmning that the magazineor holder 31 andthat theswinging arms 47 and 47 are so positioned that their ends intrude slightly "into the lower part of the magazine 31, the

lowermost can body will then rest upon the ported thereby. i Now as the driveshatt t is rotated, the

lllti arms 47 and 47 are brought closer together, by means of the linkage described above, and the stack of can bodies israised, by said in-, clined faces 50, within the magazine until the side edges of the lowermost can body reach the notches 52 in the said faces 50, whereupon said lowermost can body is squeezed edgewise,.due to the pressure exerted thereon by the continued inward movement of the said fulcrumed arms 47 and 47',

and its sides forced apart, as shown at 32 in Fig. 3 of the drawings.

Further movement of the drive-shaft 4, through the medium ofthe eccentric 43, the

I rod 41, and the lever 38, causes the slide 35, carrying the pointed rods '44 and the born 45,

tomove inwardly, that is toward the magazine, while the swinging: arms 47 and 47. re-

mainin the position shown in Fig. 3 of the drawings.

- This inward movement of the slide 35. forces the pointed rods 44 and the horn between the adjacent sides of the slightly spread can body 32, and by so doing further spreads or opens thesame, as shown in Fig. 2 of the drawings. I I

After passing sufficiently far into the can body 32 to open the same evenly throughout its length, the rods 44 and the, 0m 45' are withdrawn by the outward movement of the slide 35, the partially opened can body 32 "being retained within the magazine by the stripp r-p1ate.30,'and the arms47 and 47 by the action of the cam 62, are swung outwardly, thus allowing the stack of can bod ieswithin the magazine 31 to drop until the lowermost, partially openedcan body assumes the position32", Fig, 3 or the drawin s, and rests upon the inwardly-projecting is gas 33. The arms 47 and 47 are then again. swung inwardly, and the inclined faces'50, engaging the flattened can body immediately above the lowermost partially opened can body, raise the entire stack with-- in the magazine, with the'excepti'on of said lowermost'partially opened canbody, and, by reason of the pressure on the edges of the i flattened body resting within the notches 52 of the said swinging arms, compress the can body 32 immediately above the released and partially reformed can body 32 asindicated in Fig. 3 of the drawings.

The next inward movement of the slide 35, which introduces the opening rods 44 and horn 45 into the second can body 32 also brings the pushenarm's 46 into engagement with thapartiallyopened and released lowermost can body 32-,and thereby forces said can body 32 from within the magazine 31 onto the mandrel 12, as shown in Fig. 2 of the drawings.

These operations are repeated at every inward stroke of the slide 35. That is, a can body 32, which has been slightly spread by the arms 47 and 47, is further opened by the cylindrical body 32,

, is forced onto a mandrel 12 which has been brought into the position A,.in axial alinement with the partially opened can body 32 Fig. 3 of the drawings, by partial rotation of theturretlO. I

During the next complete reciprocating stroke of the slide 35, subsequent to forcing the can body 32* onto the mandrel 12 at the position A,-Fig. 3 of the drawings, the turret 10 is step-rotated to bring said mandrel to the position B, during which time the can body on said mandrel is not acted on.

, On the next stroke, however, the mandrel 12, with the can :body thereon, assumes the position C, and said can body is brought into contact with the rotating ironing roller 20. The said can body and the mandrel 12 on which it is supported, are revolved by the frictional contact ofthe can body with the said ironing roller 20, and said can body is thereby ironed out into a substantially true ret to position D,.after which, by the, steprotationsof the turret 10, the mandrel carrying the ironed can body 32 position designated by the letter E, Fig. 3 of the-drawings, where it is discharged from the mandrel 12 by the at this moment is thrown outwardly by the movement of the reciprocating ejector rod 63, actuated by the hereinbefore described means.

It will be readily understood from the foregoing that, when themachine is in operation, a number of can bodies are being acted on simultaneously, each in a difi'erent stage of reformation; I

During every complete stroke of the slide 35, the turret 10 is advanced-an amount equal to the angular distance between the mandrels thereon, so that at every such stroke, one flattenedcan body is brought into the sphere of action of the machine from the magazine 31*, and one reformed can body is discharged from the mandrel at the position The particular form of machine herein described is that which is deemed to be most practicable. It is understood, however, that variations may be made in the construction and arrangement of the working parts of the machine, without altering or in any way affecting the essential principles of the invention, and I therefore do not wish to be and carried by the tur-- is brought into ejector arm 64, which construed as limiting or restricting the "invention in this regar Having thus described the invention what I fit) can bodies in an axial directionto-said receiving and holding means, and means associated therewith for engaging with the surface of a cam body for. ironing the same into substantially cylindrical form, and means for spreading deformed can bodies prior to their reception on said holding means.
